Ineed major what is the area of a circle with a diameter of 13.2 cm? use 3.14 for pi and round your final answer to the nearest hundredth. enter your answer in the box. which explanation can be used to derive the formula for the circumference of a circle? a. find the length of the diameter and double this amount. subtract it from the length of the circumference. set an equation to show the difference equaling the ratio between a circumference and radius. then rearrange the equation to solve for the circumference. b. find the length of the radius. then find the circumference. use the square of the radius to set up an equation showing the relationship that the square of the radius equals the π times circumference. then rearrange the equation to equal the circumference. c. find the length of the radius and the area of the circle. divide the area by the radius to get a quotient of π . write an equation showing the area of a circle equals this quotient times the radius. then substitute the area for 3 times the circumference and rearrange the equation to equal the circumference. d. find the length of the diameter and the length of the circumference of the circle. divide the length of the circumference by the length of the diameter. set up an equation showing the ratio of the circumference to the diameter equal to π . then rearrange the equation by solving it for the circumference. substitute 2 times the radius for the diameter. a regular polygon inscribed in a circle can be used to derive the formula for the area of a circle. the polygon area can be expressed in terms of the area of a triangle. let s be the side length of the polygon, let r be the hypotenuse of the right triangle, let h be the height of the triangle, and let n be the number of sides of the regular polygon. polygon area = n(1/2*sh) which statement is true? as h increases, the area of the regular polygon approaches the area of the circle. as s increases, the area of the regular polygon approaches the area of the circle. as n increases, the area of the regular polygon approaches the area of the circle. as r increases, the area of the regular polygon approaches the area of the circle. (has picture) what is the area of a circle whose radius is 5 ft? 5π ft² 10π ft² 20π ft² 25π ft² the circumference of a circle is 5π cm. what is the area of the circle? 25π cm² 10π cm² 6.25π cm² 2.5π cm²
